Just a thought.....when it gets totally washed out
with SSB all 24 hours how are you going to clean it out? People in general dont
follow gentlemen's agreements they were not party too.....and "it doesnt say I
cant in the licence".
I fear that, though what you suggest would work, it
might encourage mayhem. I would prefer to see those who feel uncomfortable using
a morse key on other bands, improve their skill on 475 by not being
under HF-band like pressure. I dont listen there now but 10MHz used to be a
guide for what you can expect wher SSB is not actually banned from a narrow
band. Dont forget, to SSB-only ops CW is just interference. The plus point
is they will have to make a transverter first, but then a few badly aligned
tranverters on SSB could be a disaster. I think the Swedish station was was Gus
SM?BHZ, and the SSB wiped out several DX CW qsos I knew of at the time. It was a
commercial licence not an amateur one, so voice ID may have been in
the conditions.

Hi Graham Geri and all
Warren has seen SSB first hand on the MF QRG and we have this side
also.There was an SM station (call sign forgotten?) in the early days of
500 that added an SSB anouncement on his beacon and it worked
well.
To my spec. :- "One SSB channel at the high edge of the band
only used during daylight hours no DXing!" add " Use VOX, no monologuing
allowed" to be a laissez faire operation no band plan, but fair
play!.73 es GL es HNY Pete M0FMT IO91UX

800 Hz B/W ... May be this is
something 'Wolf' can code for you ? a
b/w compression / expansion module in SL , to limit
the tx b/w to 800 Hz must be possible
to divide by 3 and mult by 3
with a linear shift as well ?

Hi,
I kind of like the idea of an SSB channel. I
just pulled out the conditions of my first secial license for 160m from 1973
or 1974. That said 1815 to 1835 kHz with 10 Watts in CW, additionally one
SSB channel for 1832 to 1835 kHz, so why not trying this on 630m, too? Here
in Germany we are currently limited to 800 Hz bandwidt but I am sure we can
sork towards a special license under certain conditions such as daylight
operation only .. sounds good to me!

Hi Pete
Its quite obvious that the allocation
is quite able to support
normal armature activity , and why not
? its no longer a experimental allocation , its just the
same as 10 or top band , un expected
results today though ! ssb sounds odd ,
may be as the path is stable ,
sstv ? must be a narrow mode , and the
'new' digital voice is 2KHz , but that
requires a linear Tx path
As for the band edge
I'm straining to find a
engineering reason , that wspr and
qrss has decided to run mid band ? Im sure
users had a reasonable discussion at the
introduction of the band , to place the
modes at the edges , with live cw a the
lower portion ? its well know that
these long carrier modes cause
disruption to other band users and are
well placed at the band edges ,
'vanity beacons' is a term I have seen
noted in referral, as occupancy increases , by users
not linked or even aware of
discussions taking place on these groups , i'm
sure there will be problems leading
to the introduction of band plan's ,
for some the plans form part of the
licence conditions ..
Is Opera a vanity system ? , actually no,
it compliments ros- data mode in that
the ave s/n readings can be used to
determine if a path will support
the data mode , each having the
same averaging s/n reading taken along
the time line ,

Hi all
One SSB channel at the high edge of the band only used during
daylight hours no DXing!

Quite intriguing propagation on this
'new' band
From some unexpected early 600 mile
+ Opera decodes last night ,
to several wspr TA decodes ,
[G8's again ..] to
today's test with Gary using
USB-SSB voice ,
Where as at 1300z we
had 5/9 signals each way as
expected over 25 miles , GI3PDN
Ray , called on CW , to give a
report of 5/9 across the Irish Sea ,
some 100 miles for our two signals ,
his CW also in the 5/9/9 region, one
wonders how far inland the signals
travelled ?
After a short 3 way qso, we closed
the test round 1330z , may not of
been quite as sociable after dark ,
but with a small Ae , 40 x 70 ft iv
L and 35 ft Top load vert ,
50 watts pep , results defiantly
superior to say 160 mtrs using
the same Ae's
